The word(s) "but" appears 932 time(s) in 837 verse(s) in Quran in Muhammad Habib Shakir translation.

(621) It is nothing but a reminder to the nations;

(622) He has created you from a single being, then made its mate of the same (kind), and He has made for you eight of the cattle in pairs. He creates you in the wombs of your mothers-- a creation after a creation-- in triple darkness; that is Allah your Lord, His is the kingdom; there is no god but He; whence are you then turned away?

(623) but (as for) those who are careful of (their duty to) their Lord, they shall have high places, above them higher places, built (for them), beneath which flow rivers; (this is) the promise of Allah: Allah will not fail in (His) promise.

(624) So Allah made them taste the disgrace in this world's life, and certainly the punishment of the hereafter is greater; did they but know!

(625) And whom Allah guides, there is none that can lead him astray; is not Allah Mighty, the Lord of retribution?

(626) So when harm afflicts a man he calls upon Us; then, when We give him a favor from Us, he says: I have been given it only by means of knowledge. Nay, it is a trial, but most of them do not know.

(627) Those before them did say it indeed, but what they earned availed them not.

(628) Aye! My communications came to you, but you rejected them, and you were proud and you were one of the unbelievers.

(629) Nay! but serve Allah alone and be of the thankful.

(630) And those who disbelieve shall be driven to hell in companies; until, when they come to it, its doors shall be opened, and the keepers of it shall say to them: Did not there come to you apostles from among you reciting to you the communications of your Lord and warning you of the meeting of this day of yours? They shall say: Yea! but the sentence of punishment was due against the unbelievers.
